CUCKOO-CLOCK.

SPECIFICATION forming part of Letters Patent No. 465,441, dated December15, 1891.

Application iiled March 18, 1891. Serial No. 385.566. (Model.)

To CLM whom t may concern:

Be it known that I, THEODOR VEISSER, a subject of the Emperor ofGermany, residing at Vhrenbach, Grand Duchy of Baden, Germany, haveinvented certain new and useful Improvements in Clocks, of which thefollowing is a specification.

My invention has for its object to provide the striking-train of clockswith a device ro which will imitate the cry of the cuckoo by means of asingle whistle at every action of the striking-train. This newarrangement, compared with the hitherto known construction ofcuckoo-clocks, all of which are pror5 videdwith two whistles, presentsthe advantage that considerable less room is required, and thatconsequently cuckoo-clocks may be made of a size only half of that ofthe hitherto known construction, an advantage which is 2o highlyappreciated by the clockmakers. Moreover-,thecuckoo-cryof myimprovedclock is a great deal more natural.

In the annexed drawings, which form a part of this specification, andwherein like parts z 5 are designated by like letters of referencethroughout all the figures, Figure 1 is a back view of a clock-work, thewhistle being shown in section, the mechanism being in normal condition,portions being shown in dotted 3o lines. Fig. 2 is a plan view of theclock-work. Fig. 3 is a sectional elevation showing the mechanism inoperating position, portion of the whistle being shown in section andportion in dotted lines. Fig. 4 is a detail of the 3 5 striking-wheel.Fig. 5 is a plan detail of what is shown in Fig. 4.

In the drawings, the letter S illustrates a clock mechanism mounted inthe frame T, and which acts in the usual manner on the 4o striking-wheelA, which is provided with pro-A jecting pins a, as shown. 0n these pinsrest the two levers B and C, the first B having for its purpose to openthe key or valve 7s, while the second leverC serves to operate thebellows b. The lever C, which is forked at its front end, Fig. 5, ismounted on the arbor d, which arbor carries at its other end the leverD, engaged in a loop attached to the bellows b. The lever B is mountedon the arbor e,

and on the other end of this arbor is fixed the 5o lever E, engaged in aloop of the key-arm 7c. The whistle F, which receives the air from thebellows b, is tuned in such a manner that if the key is opened itproduces the high sound of the cuckoo-cry and if the key is closed thelow sound of the same. When the striking mechanism enters intooperation, the two levers B and C are iirst raised, whereby the bellowsh is inflated and the key 7U is opened, the forked lever C restingmeanwhile with its lower prong on one of the pins a Iof wheel A, andwhen this wheel rotates this prong will of course be released from thepin, which causes the bellows to be half-way lowered, thereby producingthe high sound of the cry. By the further rotation of the wheel thelever C is again slightly raised through its upper prong, and at thesame time the lever B is released from the pin on which it rests, whichcauses the key 7c to be closed. 7o Slightly subsequent thereto the upperprong of the lever C is released from pin a, which causes the completelowering of the bellows b, and thereby produces the lower sound of thecry, the key 7s being now closed. t A rod r is, as usual, attached tothe bellows, which produces in a well-known manner the movements of thecuckoo. A lever s is provided to move the cuckoo laterally and isactuated by the clock mechanism. 8o

IIaving thus described my invention, what I claim as new, and desire tosecure by Let'- ters Patent of the United States, is

l. In a cuckoo-clock, the combination, with a single whistle forproducing the cuckoo-cry 8 5 and a key or valve therefor which isoperatively connected with the striking-train of the clock by meansincluding a lever coacting with the strikingwheel, whereby said key orvalve is opened and closed during the operation of such striking-train,of a single bellows operatively connected with the strikingtrain bymeans including a forked lever, which in its co-operation with thestrikingtrain imparts two impulses to the bellows, one of which passesthrough the whistle when the key or valve is opened and the other whenit is closed, substantially as set forth.

2. The eombinatiomwith the striking-train Wheel A, and the free end oflever' D coactineluding Wheel A, provided with projecting ing' with a,loop on the bellows, substantlztlly pins, as shown, and a valved Whistleand :t as set forth. bellows in suitable Connection With each Intestimony whereof I have signed my 5 other, 0f levers B and E, mountedon the same name to this specification in the presence of 15 arbor andcooperating, respectivelv,\vith the two subscribingr Witnesses.
